Current Research

1. In poor country where vaccine is limited and not affordable, disease could be spread easily. A research study attempts to prove that a mucosal vaccine against Streptococcus pneumoniae using lactococcu lactis is more effective than vaccination with purified live antigen. The result shows that L. lactis has more potential and safety in developing vaccine in human and should be considered to be used against other pathogens.
